Vladimir Steshin updated IGNITE-21656:
--------------------------------------
Description:
Ignite fails to create dump of cache with a node filter. If there is no
partitions on some cone, we assign the empty sat an the snapshot task result:
{code:java}
if (parts.isEmpty() && !withMetaStorage)
task0 = new GridFinishedFuture<>(Collections.emptySet());
else {
...
}
{code}
Cache dump doesn't contain the metastoreage. Further, we may cast the result to
{code:java}
SnapshotFutureTaskResult res = (SnapshotFutureTaskResult)task0.result();
{code}
but it is a
{code:java}
Collections#EMPTY_SET
{code}
Stacktrace:
{code:java}
